Description

Technical Field

[0001] The utility model relates to the technical field of grinding and polishing of optical glass lenses, in particular to a swing rod device for an optical glass lens grinding and polishing machine. Background Technique

[0002] The swing rod device for an optical glass lens grinding and polishing machine usually consists of a support structure and a swingable arm. Tools for contacting and polishing the lens (such as abrasive discs or polishing pads) are installed on the arm. By adjusting the movement range and angle of the swing rod, uniform polishing of the lens can be achieved.

[0003] A swing rod device for an optical grinding and polishing machine disclosed in the publication number CN212240412U. Although, a swing rod device for an optical grinding and polishing machine includes a swing frame, a swing rod and a stylus.

The cam mechanism is connected with a driving motor for driving its rotation. A swing rod outer sleeve is fixedly installed on the swing frame. The swing rod is rotatably installed in the swing rod outer sleeve. After the swing rod extends out of the swing rod outer sleeve, one end is used for fixedly installing the stylus, and the other end is connected with a driving component. The driving component is used for driving the swing rod to rotate in the swing rod outer sleeve. The driving component includes an actuator I and an actuator II. One ends of the actuator I and the actuator II are connected with the swing frame. In actual use, this device can ensure that the angle between the stylus and the ball mill always remains at 90°, making the force on the lens more uniform during processing and ensuring better quality of the processed lens.
